El regreso de Mary Poppins

Dick Van Dyke was offered four options for his dance scene, each with a varying degree of difficulty. He insisted on performing the hardest dance routine and refused any help from fellow cast members while filming the scene. The resulting dance scene was so well received that there were reports of audiences applauding during screenings to see the old actor dance so well for his age.

The gaslights used in the movie are all naked flames. By the 1930s, gaslights used mantles, which gave off a lot more light for less gas and didn't smoke the glass covers. Also, gaslights were largely controlled by clockwork (still used in historic areas today in London and other European cities), so the leeries' main job would have been maintenance: mantle replacement and winding the clockwork rather than daily lighting/dousing.

There is a special thanks to Jay Leno in the credits. According to Lin-Manuel Miranda, "I asked about this when I saw that! Apparently there is a car sound effect from the 1930's that they could not replicate, and someone realized Jay Leno had the car they needed to record the sound effect."
